Nope. I don't need to have such conditions on skills. I need to make change to menu look.
Or it can be this way. In fight there are choices: "fight", "skill", "defend", "item". I could use script that would change to "magic" and "martial" instead of "skill". And ability to change in that script which skills should go under magic, and which under martial. It is actually one more option added. That would probably mean adding one more tab into database called "martial". Which would be exact as skills tab, just I could copy paste martial skills into it, and leave magic skills in skill tab. Main idea is to distinct martial and magic skills. Figher would have "martial" option, and mage "magic" option in battle screen. But this way I get my battle mage having both options. You see my point?
